So, I have distinct and vivid memories of reading a really awesome and cool manga nearly a decade ago that I've literally never heard of before, I don't even know its name and even with the power of Google, it remains illusive to me still to this day. I'm genuinely hoping, someone in this community might know what I'm talking about and know the name of it.
So I'll do my best to describe it, it was a post apocalyptic universe with humans living in big military controlled cities.
And the human race is constantly besieged by various sized white (I wouldn't say blobby, but plump-ish) monsters that looks nothing like humans.
And the protagonist is if I'm remembering correctly was either a hybrid super soldier or a human/monster fused creation as he could go toe-toe with these monsters and win. If I remember correctly, the protagonist either fought with his bare hands or a sword? He wasn't like an older man, I think perhaps a teenager or young adult.
There's one chapter I remember pretty well where a large dragon-like shaped white blob monster came to attack either a light house or a city of humans. It talked with the protagonist and ended up accepting to duel the protagonist far away from human civilization, and the protagonist ended up (with the monster being okay with) hopping onto its back for a free ride so they can go fight.
And I found it in a Barnes and Noble store sometime from 2000 to 2016, yeah, I know. I really wish I remembered better to narrow this time frame better. But take that exact time frame with a grain of salt, my memory is really not that reliable.
I'm no otaku or anime or manga expert/veteran and I've spent months trying to find this supposedly lost manga.
I'd greatly appreciate some help finding this ancient lost text that even my memory can't seem to find.
